WILLIAM VENSKE, OF MINNEAPOLIS, MINNESOTA.

SLIDING GASEMENT-WINDOW.

To all whom it may concern:

Be it known that I, W'ILLIAM VnNsKn, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Sliding Casement-Windows; and I do hereby declare the following to be a full, clear, and exact illustrate the invention, like characters indi cate like parts throughout the several views.

Referring to the drawings:

Figure 1 is a View in front elevation illustrating my invention applied to the upper and the lower sash of the window; Fig. 2 is a vertical section taken on the line 00 m on Fig. 1; Fig. 3 is a horizontal section taken on the line m m onFig. 1; Fig. 4 is a horizontal section taken on the line so a on Fig.

1; Fig. 5 is a fragmentary section taken on the line 00 m on Fig. 1; Fig. 6 shows in plan or edge elevation, the several elements of the interlocking joint between the window frame and the sash, whereby swinging movements on the side from its opposite edge, are permitted; Fig. 7 is a view corresponding in the line of its section, to Fig. 3, but showing both sashes lowered, and swung partly into open positions; Fig. 8 is a View taken on the line a m on Fig. 1, when the sash are swung as shown in Fig. 7 and Figs. 9 and 10 are diagrammatic views illustrating certain relative positions of the elements shown in Fig. 6 under certain conditions hereinafter described.

As already indicated, my invention is shown and incorporated in connection with both the upper and the lower sash of a twosash window, but as the arrangement on both Sides is the same, a description of the application of one thereof, will answer for both.

The window frame is indicated as an entirety by the numeral 1, and the upper and Serial No. 841,933.

the lower sash are indicated, respectively, by the numerals 2 and 3.

Both sashes, as shown, are arranged to swing from their left hand sides, as viewed in Fig. 1, and hence, at these sides, each sash is provided with a sheet metal joint strip 4 that extends from top to bottom of the particular sash only, and is formed with a coiled or approximately cylindrical hinge portion 5 that is arranged to move pivotally in, and to slide vertically on the correspondingly coiled portion 6 of a joint strip 7, which lat-- ter is secured to the window frame and eX- tends from top to bottom thereof, so that the said sash, on the sliding hinge described, is capable of lateral swinging movements and vertical sliding movements from top to bottom of the window frame.

At the other side of the window frame, towit, as shown in Fig. 1, at the right hand side, each sash is provided also with one of the joint strips 45, and the window frame is provided with a rigidly attached joint strip 67 that corresponds to the similar joint strip on theopposite side of the window frame, with this important exception, that instead ofextending from top to bottom of the window frame, it extends downward from the top thereof, only about half way from thebottom. Normally, the coiled portion 5 of the joint strip 4 of the upper sash, is within the coiled portion 6 of the cooperating right hand joint strip 7, and the correspondingly coiled portion 8 of a supplemental joint strip 9, surrounds the said coil 6. The body of the supplemental sliding joint strip 9 is formed with an interlocking fold that works slidably in a correspondingly folded portion 10 of another joint strip 11. This joint strip 11 is secured to the right hand side of the window frame, extends from top to bottom of the window frame, and its interlocking fold 10 is countersunk into the window frame. The supplemental joint strip 9 is only approximately one-half the length of the said joint strip 11, but it is free to move vertically upward and downward thereon, and never leaves its interlocking engagement therewith, and always engages at least a portion of the cooperating right hand joint strip 7. When the said supplemental joint strip 9 is in a lowered position (which is its normal position), it constitutes a downward extension of the joint strip 7, so that when the free to swing laterally into its open position on its left hand hinge, to-wit, on the left hand joint strips 47.

Fig. 9 illustrates the relative vertical positions of theright hand joint strips 4, 7 9 and 10, when the sash is locked against swinging movements, as above noted; and Fig. 10 illustrates the relative vertical positions of said joint strips when they are in position to permit the sash to be swung laterally, as above described. The said views 9 and 10, however, do not illustrate the proper engagements of the said joint strips, but, as stated, simply the relative vertical positions. This lateral separation of the several elements has been made because said elements, when placed one over the other, make an obscure drawing in which the elements cannot be readily distinguished.

What I claim is:

1. The combination with a window frame, of a casement window sash connected to said frame at one side by a hinge permitting lateral swinging and vertical sliding movements thereon, and at its other side, connected to said window frame by the following elements, to-wit, a joint strip on said sasl1, a joint strip on said Window frame,

and a supplemental joint stri on the said latter noted joint strip, the joint strip on said sash being engageable with both of the other noted joint strips, and the said supplemental joint strips, when the sash is in one extreme position, being slidable to release the joint strip on said sash.-

2. The combination with a window frame, of a casement window sash connected to said frame at one side by a hinge permitting lateral swinging andvertical sliding movements thereon, and at its other side, connected to said window frame by the following elements, to-wit, two joint strips secured on said window frame, one extending from 5 top to bottom thereof and the other from top to about half way to bottom of said frame, of a supplemental joint strip-movable from top to bottom of the window frame and having interlocking sliding engagement with both of said relatively 'fixed' joint strips, and a joint strip on said sash having a sliding engagement with the relatively short joint strip on said frame, and with the said sliding supplemental joint strip, the

joint strip on said sash being removable with said sash to a point below the relatively short joint strip on said frame, and said supplemental joint strip being slidable upward to apoint above the joint strip on the lower sash. f 1

In testimony whereof I affix my signature in presence of two witnesses.
